Patented' nee. 20,1921.

Application filed November 15, 19530. j Serial No. IFZLLHQ.

following is a specification.

' ment outer compartment.

ln the patent No.v 1,136,818 there is described an internal combustion engine having a primary explosion chamber divided into two compartments arranged concentrically to each other, the inner one ot said compartments communicating directly with the cylinder chamber, while the outer conipartnient communicates with the said inner chamber only.

In machines constructed :in accordance with/said patent l have found that 'fluid oil may collect in the ysaidouter compartment when the engine is running light, and will causeracing ofA the engine when the fuel supply is cut oli.

To overcome said inconvenience there is provided accordfng to this 'invention a direct Veonnection between the said outer compartunburned fuel oil from collecting in said ln the accompanying drawing 'I have shown one embodiment oi my invention. Figure l is a diagrammatioal longitudinal section ot' an internal combustion engine vconstructed according to said invention.

Fig. 2 is an enlarged sectional view of the uppermost portion of the same engine.

The numeral nl represents the cylinder chamber of the engine communicating eonstantly with the inner compartmentll of a primary yetq'ilosion chamber comprising the two compartments fl and arranged concentrically to each` otlieigand ANA separated -trom each other by a sleeve' 3comniuiication between the said. compartments being provided by a space at the top of the sleeve` as well as by aperturesv formed in the walls of said sleeve.

and the cylinder chamber to prevent lmary explosion chamber,

. According to this invention not onlythe inner compartment l but also the outer comu partment 5 of the primary explosion chamber communicates directly with the cylinder chamber l, the connection between the compartment 5 and the cylinder chamber being formed by the two holes or channels 6 and 7. 1t is evident that the position and number ot such holes' or channels rnav be chosen at will. c v

The general outlines of the operation of that hind ot engines to which thev invention is applied are described in the Tatent l,l36,

S18. Due to the provision otsuch channels 6 'and 7 any fuel oil tending' to collect inthe compartment will How through V:the .chan nels into the cylinder chamber thereby eliminating the tendency for racingof the ein' gine above referred to. i

it is obvious that the invention may be applied not only to vertical engines but also to horizontal engines,"the only requirement to be satisfied in bothv cases being that the channels 6 and 7 are arranged vertically or inclined so as to permit fuel oil to ow from he compartment 5 into the cylinder chainer. y l

Having now described my invention, what I claim is In an internal combustion engine, the combination of a cylinder chamber, a pria sleeve in said primary explosion chamber secured to the bottom of said chamber and ending at a, distance 'from the top thereof, the two com pertinents ot said primary explosion charnber formed by the said sleeve communicating with each other through openings in the sleeve and further communicating separately with the said cylinder chamber.

ln testimony whereof I have signed my name..
